Adam Lambert to Guest Star on Pretty Little Liars » Gossip - He may or may not be on his way to American Idol.

But Adam Lambert is definitely stopping by Rosewood.

The singer has confirmed, via Twitter, that he will appear as himself later this year on an episode of Pretty Little Liars, the special standalone installment of the ABC Family drama based around Halloween to be specific.

"When we heard Adam was a fan of the show we knew that he would be a perfect fit for our Halloween episode," executive producer I. Marlene King told E! News of the casting. "He's oh so Rosewood!"

Look for Lambert to share a scene with Lucy Hale's Aria and to perform a pair of singles at a theme party during the hour.

This A should be slightly less scary than the one typically featured on the show.
